Abstract
von Willebrand disease (VWD) is the most common inherited bleeding disorder. The management of patients with VWD who are undergoing surgeries is crucial to prevent bleeding complications. We systematically summarized the evidence on the management of patients with VWD who are undergoing major and minor surgeries to support the development of practice guidelines. We searched Medline and EMBASE from inception through October 2019 for randomized clinical trials (RCTs), comparative observational studies, and case series that compared maintaining factor VIII (FVIII) levels or von Willebrand factor (VWF) levels at >0.50 IU/mL for at least 3 days in patients undergoing major surgery, and those with options for perioperative management of patients undergoing minor surgery. Two authors screened and abstracted data and assessed the risk of bias. We conducted meta-analyses when possible. We evaluated the certainty of the evidence using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach. We included 7 case series for major surgeries and 2 RCTs and 12 case series for minor surgeries. Very-low-certainty evidence showed that maintaining FVIII levels or VWF levels of >0.50 IU/mL for at least 3 consecutive days showed excellent hemostatic efficacy (as labeled by the researchers) after 74% to 100% of major surgeries. Low- to very-low-certainty evidence showed that prescribing tranexamic acid and increasing VWF levels to 0.50 IU/mL resulted in fewer bleeding complications after minor procedures compared with increasing VWF levels to 0.50 IU/mL alone. Given the low-quality evidence for guiding management decisions, a shared-decision model leading to individualized therapy plans will be important in patients with VWD who are undergoing surgical and invasive procedures.

The Use of Tranexamic Acid in Hip and Pelvic Fracture Surgeries. J Am Acad Orthop Surg 2021; 29:e576-e583. [PMID: 33788803 DOI: 10.5435/jaaos-d-20-00750] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/25/2020] [Accepted: 02/08/2021] [Indexed: 02/01/2023] Open
Abstract
Tranexamic acid (TXA) use has expanded across many surgical specialties. It has been shown to reduce blood loss, decrease transfusion rates, and, in some cases, improve mortality. Within orthopaedic surgery, its popularity has primarily grown within arthroplasty and spinal surgery. It has only recently gained traction within the field of orthopaedic trauma and fracture care. At this time, most literature focuses on hip fracture and pelvic trauma surgery. For hip fractures, the results are encouraging and generally support the claim that TXA may lower overall blood loss and decrease transfusions. Conversely, less support exists for TXA use in fractures of the acetabulum or pelvic ring. Based on the current fracture-related studies, TXA does not seem to carry an increased risk of thromboembolism or other complications. In addition, few studies have been noted discussing the route of administration, timing, or dosage. This article reviews the most current literature regarding TXA use in fracture care and expands on the need for further research to evaluate the role of TXA in orthopaedic trauma populations who carry a high risk for transfusion.

Safety and Efficacy of Topical Administration of Tranexamic Acid in High-Risk Patients Undergoing Posterior Lumbar Interbody Fusion Surgery. World Neurosurg 2021; 151:e621-e629. [PMID: 33940262 DOI: 10.1016/j.wneu.2021.04.088] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2021] [Revised: 04/19/2021] [Accepted: 04/20/2021] [Indexed: 11/17/2022]
Abstract
OBJECTIVE We sought to evaluate the safety and efficacy of topical administration of tranexamic acid (TXA) in high-risk patients undergoing posterior lumbar interbody fusion (PLIF) surgery. METHODS In this single-center, retrospective cohort study, a total of 120 patients with lumbar degenerative disease who had a previous history of cardiovascular or cerebrovascular embolism and who underwent single-level PLIF surgery between December 2018 and December 2019 were included and allocated to 2 groups according to whether they had been administered TXA. In the TXA group (n = 60), the wound surface was topically soaked with TXA (1 g in 100 mL of saline solution) for 5 minutes before wound closure. In the control group (n = 60), the wound surface was topically soaked with the same volume of normal saline. SPSS software, version 26.0, was employed to analyze demographics including surgical traits, blood loss, drainage, length of hospital stays (LOS), blood biochemical indices, prethrombotic state molecular markers, coagulation function, and adverse events. RESULTS Total blood loss, visible blood loss, postoperative drainage, removal time of drainage tube, and LOS were significantly lower in the TXA group than in the control group. However, there was no significant difference between the 2 groups in hidden blood loss, hepatorenal function, coagulation function, prethrombotic state molecular markers, transfusion rate, or complications during the perioperative period. CONCLUSIONS In single-level PLIF surgery, topical administration of TXA could significantly reduce total blood loss, visible blood loss, postoperative drainage, removal time of drainage tube, and LOS without increasing the risk of thromboembolic events in high-risk patients with prior histories of thrombosis.

Abstract
BACKGROUND von Willebrand disease (VWD) is a common inherited bleeding disorder. Significant variability exists in management options offered to patients. OBJECTIVE These evidence-based guidelines from the American Society of Hematology (ASH), the International Society on Thrombosis and Haemostasis (ISTH), the National Hemophilia Foundation (NHF), and the World Federation of Hemophilia (WFH) are intended to support patients, clinicians, and health care professionals in their decisions about management of VWD. METHODS ASH, ISTH, NHF, and WFH formed a multidisciplinary guideline panel. Three patient representatives were included. The panel was balanced to minimize potential bias from conflicts of interest. The University of Kansas Outcomes and Implementation Research Unit and the McMaster Grading of Recommendations Assessment, Development and Evaluation (GRADE) Centre supported the guideline development process, including performing and updating systematic evidence reviews (through November 2019). The panel prioritized clinical questions and outcomes according to their importance to clinicians and patients. The panel used the GRADE approach, including GRADE Evidence-to-Decision frameworks, to assess evidence and make recommendations, which were subject to public comment. RESULTS The panel agreed on 12 recommendations and outlined future research priorities. CONCLUSIONS These guidelines make key recommendations regarding prophylaxis for frequent recurrent bleeding, desmopressin trials to determine therapy, use of antiplatelet agents and anticoagulant therapy, target VWF and factor VIII activity levels for major surgery, strategies to reduce bleeding during minor surgery or invasive procedures, management options for heavy menstrual bleeding, management of VWD in the context of neuraxial anesthesia during labor and delivery, and management in the postpartum setting.

Bajkin B, Dougall A. Current state of play regarding dental extractions in patients with haemophilia: Consensus or evidence-based practice? A review of the literature. Haemophilia 2020; 26:183-199. [PMID: 31962377 DOI: 10.1111/hae.13928] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2019] [Revised: 12/17/2019] [Accepted: 01/03/2020] [Indexed: 11/28/2022]
Abstract
Due to the global prevalence of oral disease, tooth extraction is the most common surgical procedure required in general population thus likely to be similarly common in patients with haemophilia, especially those in older age and those living in countries with restricted resources. There are little or no consensus about optimal level and duration of factor replacement (FRP) therapy required to prevent bleeding complication following surgery and low levels of evidence to inform protocols and guidelines. The goal of this article was to review the literature regarding haematological treatment protocols and to assess their effectiveness in prevention of bleeding complications during and after tooth extractions in people with haemophilia. A total number of 29 articles were identified. Only two of the studies were randomized controlled trials, and meta-analysis was not possible. Significant heterogeneity regarding haematological regimes, dental surgical procedures, disease severity and sample size of published studies which are unable to reliably inform the provision of safe dental surgery was noted. Based on the haematological regimens, all studies were classified into one of three groups: pre- and postoperative FRP or DDAVP, single preoperative FRP or DDAVP, and no FRP treatment. The overall reported bleeding rate in case of both pre- and postoperative FRP and single dose FRP preoperative is similar, 11.9% and 11.4%, respectively, indicating that minimizing the use of clotting factor concentrate is possible if proper local haemostatic measures are provided. Strictly designed prospective studies with higher number of patients are necessary to get firm conclusions about optimal FRP treatment required to prevent bleeding complications during and after oral surgery in patients with haemophilia.

Antifibrinolytic therapy for preventing oral bleeding in patients with haemophilia or Von Willebrand disease undergoing minor oral surgery or dental extractions. Cochrane Database Syst Rev 2019; 4:CD011385.

Abstract
BACKGROUND Minor oral surgery or dental extractions (oral or dental procedures) are widely performed and can be complicated by hazardous oral bleeding, especially in people with an inherited bleeding disorder such as haemophilia or Von Willebrand disease (VWD). The amount and severity of singular bleedings depend on disease-related factors, such as the severity of the haemophilia, both local and systemic patient factors (such as periodontal inflammation, vasculopathy or platelet dysfunction) and intervention-related factors (such as the type and number of teeth extracted or the dimension of the wound surface). Similar to local haemostatic measures and suturing, antifibrinolytic therapy is a cheap, safe and potentially effective treatment to prevent bleeding complications in individuals with bleeding disorders undergoing oral or dental procedures. However, a systematic review of trials reporting outcomes after oral surgery or a dental procedure in people with an inherited bleeding disorder, with or without, the use of antifibrinolytic agents has not been performed to date. This is an update of a previously published Cochrane Review. OBJECTIVES Primarily, we aim to assess the efficacy of antifibrinolytic agents to prevent bleeding complications in people with haemophilia or VWD undergoing oral or dental procedures.Secondary objectives are to assess if antifibrinolytic agents can replace or reduce the need for clotting factor concentrate therapy in people with haemophilia or VWD and to establish the effects of these agents on bleeding in oral or dental procedures for each of these patient populations. SEARCH METHODS We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group's Coagulopathies Trials Register, compiled from electronic database searches of the Cochrane Central Register of Controlled Trials (CENTRAL), of MEDLINE and from handsearching of journals and conference abstract books. We additionally searched the reference lists of relevant articles and reviews. We searched PubMed, Embase, Cinahl and the Cochrane Library. Additional searches were performed in ClinicalTrials.gov, WHO International Clinical Trials Registry Platform (ICTRP).Date of last search of the Cystic Fibrosis and Genetic Disorders Group's Coagulopathies Trials Register: 01 March 2019. SELECTION CRITERIA Randomised and quasi-randomised controlled trials in people with haemophilia or VWD undergoing oral or dental procedures using antifibrinolytic agents (tranexamic acid or epsilon aminocaproic acid (EACA)) to prevent perioperative bleeding compared to no intervention or usual care with or without placebo. DATA COLLECTION AND ANALYSIS Two authors independently screened the titles and abstracts of all identified articles. Full texts were obtained for potentially relevant abstracts and two authors independently assessed these for inclusion based on the selection criteria. A third author verified trial eligibility. Two authors independently performed data extraction and risk of bias assessments using standardised forms. MAIN RESULTS While there were no eligible trials in people with VWD identified, two randomised, double-blind, placebo-controlled trials (total of 59 participants) in people with haemophilia undergoing dental extraction were included. One trial of tranexamic acid published in 1972 included 28 participants with mild, moderate or severe haemophilia A and B and one of EACA published in 1971 included 31 people with haemophilia with factor VIII or factor IX levels less than 15%. Overall, the two included trials showed a beneficial effect of tranexamic acid and EACA, administered systemically, in reducing the number of bleedings, the amount of blood loss and the need for therapeutic clotting factor concentrates. Regarding postoperative bleeding, the tranexamic acid trial showed a risk difference (RD) of -0.64 (95% confidence interval (CI) -0.93 to - 0.36) and the EACA trial a RD of -0.50 (95% CI 0.77 to -0.22). The combined RD of both trials was -0.57 (95% CI -0.76 to -0.37), with the quality of the evidence (GRADE) for this outcome is rated as moderate. Side effects occurred once and required stopping EACA (combined RD of -0.03 (95% CI -0.08 to 0.13). There was heterogeneity between the two trials regarding the proportion of people with severe haemophilia included, the concomitant standard therapy and fibrinolytic agent treatment regimens used. We cannot exclude that a selection bias has occurred in the EACA trial, but overall the risk of bias appeared to be low for both trials. AUTHORS' CONCLUSIONS Despite the discovery of a beneficial effect of systemically administered tranexamic acid and EACA in preventing postoperative bleeding in people with haemophilia undergoing dental extraction, the limited number of randomised controlled trials identified, in combination with the small sample sizes and heterogeneity regarding standard therapy and treatment regimens between the two trials, do not allow us to conclude definite efficacy of antifibrinolytic therapy in oral or dental procedures in people with haemophilia. No trials were identified in people with VWD.

Abstract
Background This work aimed to evaluate the efficacy and safety of routine tranexamic acid (TXA) use in elective orthopaedic lower limb joint replacement surgery. Methods This retrospective cohort study included all primary hip or knee replacement procedures by a single surgeon over a 6-year period. TXA was introduced during the study period as part of an enhanced recovery after surgery strategy. Results Of the 673 procedures, 446 cases (66.3%) received TXA. The median length of stay was 5 days (2-69) and 6 days (3-28) for the TXA and control groups, respectively (P < .001). Blood transfusion was required for 28 (6.3%) of the TXA cases versus 40 (17.6%) controls (P < .001). Complication rates were similar irrespective of TXA status. At multivariate analysis, TXA was significantly and independently associated with fewer blood transfusions (hazard ratio 0.309, 95% confidence interval: 0.168-0.568, P < .001), with a number needed to treat of 9 cases. TXA use was estimated to save between £67.89 and £155.90 per case. Conclusions Routine prophylactic TXA administration for elective primary hip and knee replacement reduces the likelihood of postoperative transfusion with a number needed to treat of 9. Cost savings may be as high as £155.90 per case, and no safety concerns were noted.

Abstract
The use of tranexamic acid (TXA) in the treatment of trauma patients was relatively unexplored until the landmark Clinical Randomisation of an Antifibrinolytic in Significant Haemorrhage-2 (CRASH-2) trial in 2010 demonstrated a reduction in mortality with the use of TXA. Although this trial was a randomized, double-blinded, placebo-controlled study incorporating >20,000 patients, numerous limitations and weaknesses have been described. As a result, additional studies have followed, delineating the potential risks and benefits of TXA administration. A systematic review of the literature to date reveals a mortality benefit of early (ideally <1 hour and no later than 3 hours after injury) TXA administration in the treatment of severely injured trauma patients (systolic blood pressure <90 mm Hg, heart rate >110). Combined with abundant literature showing a reduction in bleeding in elective surgery, the most significant benefit may be administration of TXA before the patient goes into shock. Those trials that failed to show a mortality benefit of TXA in the treatment of hemorrhagic shock acknowledged that most patients received blood products before TXA administration, thus confounding the results. Although the use of prehospital TXA in the severely injured trauma patient will become more clear with the trauma studies currently underway, the current literature supports the use of prehospital TXA in this high-risk population. We recommend considering a 1 g TXA bolus en route to definitive care in high-risk patients and withholding subsequent doses until hyperfibrinolysis is confirmed by thromboelastography.

One trial of tranexamic acid published in 1972 included 28 participants with mild, moderate or severe haemophilia A and B and one of epsilon aminocaproic acid published in 1971 included 31 people with haemophilia with factor VIII or factor IX levels less than 15%. Overall, the two included trials showed a beneficial effect of tranexamic acid and EACA, administered systemically, in reducing the number of bleedings, the amount of blood loss and the need for therapeutic clotting factor concentrates. Regarding postoperative bleeding, the tranexamic acid trial showed a risk difference of -0.64 (95% confidence interval -0.93 to - 0.36) and the EACA trial a risk difference of -0.50 (95% confidence interval 0.77 to -0.22). The combined risk difference of both trials was -0.57 (95% confidence interval -0.76 to -0.37), with the quality of the evidence (GRADE) for this outcome is rated as moderate. Side effects occurred once and required stopping epsilon aminocaproic acid (combined risk difference of -0.03 (95% CI -0.08 to 0.13). There was heterogeneity between the two trials regarding the proportion of people with severe haemophilia included, the concomitant standard therapy and fibrinolytic agent treatment regimens used. We cannot exclude that a selection bias has occurred in the epsilon aminocaproic acid trial, but overall the risk of bias appeared to be low for both trials. AUTHORS' CONCLUSIONS Despite the discovery of a beneficial effect of systemically administered tranexamic acid and epsilon aminocaproic acid in preventing postoperative bleeding in people with haemophilia undergoing dental extraction, the limited number of randomised controlled trials identified, in combination with the small sample sizes and heterogeneity regarding standard therapy and treatment regimens between the two trials, do not allow us to conclude definite efficacy of antifibrinolytic therapy in oral or dental procedures in people with haemophilia. No trials were identified in people with Von Willebrand disease.

Abstract
BACKGROUND In people with haemophilia or other congenital bleeding disorders undergoing surgical interventions, haemostatic treatment is needed in order to correct the underlying coagulation abnormalities and minimise the bleeding risk. This treatment varies according to the specific haemostatic defect, its severity and the type of surgical procedure. The aim of treatment is to ensure adequate haemostatic coverage for as long as the bleeding risk persists and until wound healing is complete. OBJECTIVES To assess the effectiveness and safety of different haemostatic regimens (type, dose and duration, modality of administration and target haemostatic levels) administered in people with haemophilia or other congenital bleeding disorders for preventing bleeding complications during and after surgical procedures. SEARCH METHODS We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group's Coagulopathies Trials Register, compiled from electronic database searches and handsearching of journals and conference abstract books. We also searched the reference lists of relevant articles and reviews.Date of the last search: 20 November 2014. SELECTION CRITERIA Randomised and quasi-randomised controlled trials comparing any hemostatic treatment regimen to no treatment or to another active regimen in children and adults with haemophilia or other congenital bleeding disorders undergoing any surgical intervention. DATA COLLECTION AND ANALYSIS Two authors independently assessed trials (eligibility and risks of bias) and extracted data. Meta-analyses were performed on available and relevant data. MAIN RESULTS Of the 16 identified trials, four (112 participants) were eligible for inclusion.Two trials evaluated 59 people with haemophilia A and B undergoing 63 dental extractions. Trials compared the use of a different type (tranexamic acid or epsilon-aminocaproic acid) and regimen of antifibrinolytic agents as haemostatic support to the initial replacement treatment. Neither trial specifically addressed mortality (one of this review's primary outcomes); however, in the frame of safety assessments, no fatal adverse events were reported. The second primary outcome of blood loss was assessed after surgery and these trials showed the reduction of blood loss and requirement of post-operative replacement treatment in people receiving antifibrinolytic agents compared with placebo. The remaining primary outcome of need for re-intervention was not reported by either trial.Two trials reported on 53 people with haemophilia A and B with inhibitors treated with different regimens of recombinant activated factor VII (rFVIIa) for haemostatic coverage of 33 major and 20 minor surgical interventions. Neither of the included trials specifically addressed any of the review's primary outcomes (mortality, blood loss and need for re-intervention). In one trial a high-dose rFVIIa regimen (90 μg/kg) was compared with a low-dose regimen (35 μg/kg); the higher dose showed increased haemostatic efficacy, in particular in major surgery, with shorter duration of treatment, similar total dose of rFVIIa administered and similar safety levels. In the second trial, bolus infusion and continuous infusion of rFVIIa were compared, showing similar haemostatic efficacy, duration of treatment and safety. AUTHORS' CONCLUSIONS There is insufficient evidence from randomised controlled trials to assess the most effective and safe haemostatic treatment to prevent bleeding in people with haemophilia or other congenital bleeding disorders undergoing surgical procedures. Ideally large, adequately powered, and well-designed randomised controlled trials would be needed, in particular to address the cost-effectiveness of such demanding treatments in the light of the increasing present economic constraints, and to explore the new challenge of ageing patients with haemophilia or other congenital bleeding disorders. However, performing such trials is always a complex task in this setting and presently does not appear to be a clinical and research priority. Indeed, major and minor surgeries are effectively and safely performed in these individuals in clinical practice, with the numerous national and international recommendations and guidelines providing regimens for treatment in this setting mainly based on data from observational, uncontrolled studies.

Abstract
BACKGROUND Tranexamic acid (TXA) is an antifibrinolytic that inhibits both plasminogen activation and plasmin activity, thus preventing clot break-down rather than promoting new clot formation. TXA has been used around the world to safely control bleeding since the 1960s. A large randomized trial recently conducted in >20,000 trauma patients adds to the large body of data documenting the usefulness of TXA in promoting hemostasis. METHODS We reviewed the literature describing use of TXA in a variety of settings including trauma. RESULTS TXA has been safely used across a wide range of clinical settings to control hemorrhage. The results of a large, randomized, placebo-controlled trial support the use of TXA to treat bleeding trauma patients. CONCLUSIONS This inexpensive and safe drug should be incorporated into trauma clinical practice guidelines and treatment protocols. Further research on possible alternate mechanisms of action and dosing regimens for TXA should be undertaken. Concurrent to these endeavors, TXA should be adopted for use in bleeding trauma patients because it is the only drug with prospective clinical evidence to support this application.

Abstract
We evaluated the effectiveness of desmopressin to control bleeding of patients with coagulation defects during dental surgery. Thirty-five patients, mainly with moderate and mild hemophilia and Willebrand disease, were undergoing dental extractions (over 80 extractions in total). Bleeding was successfully prevented in 28 patients with the use of a combined treatment incorporating IV desmopressin, an antifibrinolytic agent (tranexamic acid), and local methods (surgical glue and compression techniques). Seven patients had a bleeding episode after dental extraction, which was controlled in two cases by repeated injection of desmopressin and in another two by local methods; Factor VIII substitutive treatment was needed in only three patients. Desmopressin offers an alternative to blood products to control bleeding risk in patients with moderate and mild coagulation defects. Our experience tends to specify the mode of administration of both desmopressin and the associated treatments. Our findings suggest that desmopressin can be used in conjunction with other treatments to prevent bleeding in patients with coagulation defects who undergo dental surgery. This work highlights the concept of multifactorial medical care of these patients in which desmopressin plays a major role.

Abstract
The objective of the study was to investigate the content of tranexamic acid in plasma and in mixed, unstimulated whole saliva after oral administration and mouth rinsing. Ten healthy volunteers each received 1 g of tranexamic acid orally, whereas 20 healthy volunteers rinsed their mouths with 10 mL of a 5% aqueous tranexamic acid solution for two minutes. Blood and saliva were collected 30, 60, 120, 240, 360, and 480 minutes after administration of tranexamic acid. Samples of blood and saliva were analyzed for tranexamic acid content by electron capture gas chromatography. After oral administration, the mean plasma concentration of tranexamic acid reached its maximum after 120 minutes at approximately 7 micrograms/mL, whereas none of the saliva samples contained tranexamic acid at detectable levels. After mouth rinse, the plasma concentrations remained below 2 micrograms/mL, whereas the concentrations found in saliva initially were very high (after 30 minutes mean concentration above 200 micrograms/mL) and remained at a therapeutic level for more than two hours. These findings indicate, that fibrinolysis in the oral cavity can be inhibited only by local administration of tranexamic acid. This finding may be of significance when the drug is used for prevention and treatment of bleeding in the oral cavity in patients with coagulation defects.

Abstract
The objectives of the present clinical investigation were to examine the effects in hemophiliacs of local antifibrinolytic treatment with tranexamic acid on the incidence of postoperative bleeding after oral surgery and on the amount of replacement therapy needed to control bleeding. The study compared three groups of patients. The patients in group A received high doses of factor concentrate and systemic antifibrinolytic treatment with tranexamic acid. In group B local antifibrinolytic treatment with tranexamic acid was added to the treatment received by group A. Group C received replacement therapy to raise factor levels to approximately 10% of the normal value perioperatively, combined with systemic and local antifibrinolytic treatment (mouth rinse) with tranexamic acid. The study demonstrated that local antifibrinolytic therapy with tranexamic acid as a supplement to the currently used systemic therapy significantly reduces the incidence of postoperative bleeding. The results of the study further suggest that replacement therapy can be reduced during oral surgery in the hemophilic patient provided that local and systemic inhibition of fibrinolysis is instituted.

Abstract
During the past ten years we have witnessed a remarkable reduction in complications following dental extractions in patients with hemophilia. Thirty-six of 100 patients experienced delayed bleeding during the first half of this period; fourteen of 112 patients had a hemorrhagic problem after extraction during the second half. From a major undertaking involving hospitalization and general anesthesia, it has become a simple procedure in the outpatient office. During the entire period, no changes were made in the transfusion policy or in the oral administration of antifibrinolytic agents. Factors contributing to the favorable evolution have been the increasing experience of the oral surgeon, the improving dental status of our hemophilia patients, prophylactic measures to reduce gingival inflammation, and changes in the composition and amount of material used to pack the dental sockets.

Abstract
The requirements for factor VIII (AHF) or factor IX (PTC) of hemophilic patients undergoing dental extractions were evaluated to determine the minimum effective regimen. Sixteen patients underwent 19 operative procedures. The mean total dose of factor VIII or IX was 45.8 U/kg for 11 procedures with preoperative replacement therapy and 34.5 U/kg for the 8 without. Four patients received no replacement therapy at all. Our results compared favorably to published studies employing factor replacement alone or in combination with antifibrinolytic agents such as epsilon-amino-caproic acid (EACA), with respect to blood products utilized and duration of hospitalization. However, our patients received less factor replacement than usually suggested. General anesthesia with intubation, a common recommendation, was not required in any patients. Dental extractions can be carried out in hemophiliacs using less replacement therapy than currently recommended. In some circumstances, no replacement therapy may be necessary. The reported efficacy of antifibrinolytic agents in reducing the requirement for replacement therapy is difficult to assess because of the relatively large amount of prophylactic factor replacement used in conjunction with these agents.

Abstract
Two cases of thrombasthenia, a rare hereditary disorder of platelet function, are presented. The oral surgical and dental management of these cases is discussed in the light of the development of isoantibodies to transfused platelets in one of the cases and in another case encountered. The problems of obtaining donor platelets matched for platelet and HL-A antigens are discussed. Emphasis is placed on the use of local hemostatic measures and antifibrinolytic agents in the management of hemorrhage in this disorder and the avoidance of platelet transfusions as far as possible. Conservative dentistry and early preventive dental advice are considered desirable in order to avoid extractions.
